Patent CA-2510590-C (CA)
Inventor: WINCHESTER JOHN O
IPC: C04B28/04
Filed: 1998-08-13
Granted: 2006-11-28
Abstract: Disclosed is a method for providing an improved cementitious product (56) which includes improved surface characteristics such as skid resistance, as well as improved structural characteristics such as flexural toughness. The product (56) is provided by the inclusion of skid-resistant particles within an uncured cement product, such that the product eventually cures with the skid-resistant particles fixed at, and adjacent to, the surface, providing improved skid resistance to the cement product and its supporting surface, which could be a pedestrian sidewalk, steps (54), a vehicle roadway, handicapped ramps, or other surfaces where skid resistance is required. The product (56) is desirably softer in structure than traditional concrete structures to allow for desirable wearing by traffic thereon to continuously expose new rubber particles, while still having integral properties which discourage pullout of the particles.

Abstract: A method for communicating with a downhole tool located in a subterranean borehole is disclosed. Exemplary embodiments of the method include encoding data and/or commands in a sequence of varying drill string rotation rates and drilling fluid flow rates. The varying rotation rates and flow rates are measured downhole and processed to decode the data and/or the commands. In one exemplary embodiment, commands in the form of relative changes to current steering tool offset and tool face settings are encoded and transmitted downhole. Such commands may then be executed, for example, to change the steering tool settings and thus the direction of drilling. Exemplary embodiments of this invention advantageously provide for quick and accurate communication with a downhole tool.

Granted: 2010-11-30
Abstract: A passive exhaust system is described that provides effective infrared signature suppression without affecting radar cross-section while maintaining stable function in crosswinds. A passive exhaust system may include an array of ducts with each duct having a primary and secondary nozzle. Central ducts draw in ambient cooling air to create a thick cooling film along exterior surfaces and cause plume dilution, stabilize the plume flow in a crosswind, and prevent heating of visible surfaces. Visible surfaces may incorporate radar absorbing materials and may be inclined at an angle or fabricated with a diffuse surface to prevent specular reflection. Visible surfaces may be constructed from or covered with low infrared emissivity materials. A variable passive flow controller ensures a sufficient velocity exhaust flow.

Abstract: A system of retrieving and presenting partial (skipped) document content is provided, which parses content of an electronic document and generates a document object model (DOM) representation of the document, where each source and destination target is assigned a document object model identifier (DOM ID). The DOM is paginated in computer memory into chunks so as to update each DOM ID with an additional information attribute containing the chunk index that relates the DOM ID and the corresponding chunk index. When a device requests specific content corresponding to the DOM ID, the chunk index value indicates the correct chunk to be returned to the device.  The device requests, parses and displays an initial chunk of document content, and records navigational information provided in the form of link information containing corresponding DOM ID and chunk index information.

Each of the plates have outer side edges having opposed sloped edge portions on a respective side of an arresting raised projection formed in the outer edge in a mid-section thereof. The sloped edge portions slope inwardly towards a respective one of the opposed ends of the connector member. The connector engages opposed end portions of pipes coupled together by a frictional retaining force exerted on the inner walls at opposed ends of the coupled pipes.

Abstract: A portable system and method for measuring the concentration of multiple chemical or biological substances where an onsite analysis of such substances is needed. The new and original handheld sensor system uses a disposable optical test element and a spectroscopic detector that measures the test element response to specific analytes through a change in light absorbance, luminescence, and other forms of light-based response. In this way, reflection light intensities indicative of the test element response can be used to measure the concentration of the target analytes. The sensor system is also capable of being interfaced to an information processing unit or computer so that analytical data can be manipulated or stored electronically.

Title: Apparatus for the humidification of the air in a cabin of a passenger or cargo aircraft
Inventor: DECHOW MARTIN
IPC: B05B1/24
Filed: 2005-05-11
Granted: 2009-07-14
Abstract: A humidification apparatus which makes possible individual humidification of the air in a cabin of a passenger or cargo aircraft makes available a conditioning fluid to be ejected into the cabin from an outlet nozzle (10).  The conditioning fluid contains as a component water which is sprayed at a spraying point in very close spatial association with the outlet nozzle (10).  To avoid undesired local cooling of the cabin air caused by vaporisation of the sprayed water, the conditioning fluid contains an air flow conducted to the outlet nozzle, into which the water is sprayed. The air flow is supplied to the spraying point at a temperature which is higher by a defined amount than a desired effective temperature of the air flow after emerging from the outlet nozzle. In another embodiment the conditioning fluid contains water as its only component, the water being sprayed at a temperature above the cabin temperature.

Abstract: Un détecteur de transpondeur RFID est proposé avec un système d'oscillateur couplé. Les premières et secondes paires couplées de CL du système produisent un signal de détection chaque fois qu'une combinaison de pulsations est appliquée à la paire de CL. L'application de pulsations est répétée périodiquement pour produire une séquence aux signaux de détection avec deux premières et secondes fréquences de détection différentes. La transmission de la séquence de signaux de détection se traduit par un premier et un second signal de réponse qui correspondent à la première et à la seconde fréquence de détection à la paire de CL. Les valeurs d'un paramètre de détection présélectionné pour les signaux de détection sont comparées aux valeurs du paramètre de détection pour les signaux de réponse pour déterminer si un transpondeur avec une fréquence de résonance de transpondeur qui correspond à la première ou à la seconde fréquence de détection est présent dans un espace proximal du détecteur du transpondeur.

Abstract: A network security device which acts as an "airlock" for traffic between a communications device and a network. Data is screened using rules based analysis by the security device to counter various threats, including viruses, phishing, attempts to "hijack" communications, communications with known malicious addresses or unknown addresses, and transmission of sensitive information. Data packets can be reassembled into files for screening, and decoded or expanded as necessary, but is never executed. The data path for the data being screened is kept separate from the operations of the network security device itself, so that the device is incorruptible - its programming cannot be compromised from outside sources. Updates for rules and entry of sensitive data for screening, etc., must be done through a physical interface, not via the normal data communications channel. The device is invisible - it cannot be "seen" by the network, and thus cannot be attacked.
